Fire Alarm Plan Check in Los Angeles: Common Reasons Plans Get Rejected

Why do fire alarm plans get rejected or returned for corrections in Los Angeles? The most common reasons include incomplete plans, missing or inconsistent information, incorrect device locations, inadequate system calculations, coordination problems with other building systems, and failure to address applicable fire and electrical requirements.
For projects within the City of Los Angeles, fire alarm plans may be reviewed through the Los Angeles Fire Department (LAFD) and the Los Angeles Department of Building and Safety (LADBS), depending on the project and scope. LAFD states that its Fire Life Safety Plan Review team reviews applicable new construction, change-of-use, and remodeling projects, including fire alarm and other fire/life-safety systems.
LAFD also explains that one of the purposes of plan check is to review plans submitted for permits and issue correction notices when requirements are not satisfied.
For property owners, developers, general contractors, and property managers, understanding the common causes of fire alarm plan corrections can help reduce delays and avoid unnecessary redesign.
Cyber Shield Security works with customers throughout Los Angeles and surrounding areas on fire alarm and security system projects.

Quick Answer: Why Do Fire Alarm Plans Get Rejected in Los Angeles?
Fire alarm plans can be returned for corrections when the submitted design does not provide enough information for the reviewing authority to verify compliance.
Common issues include:
Incomplete floor plans
Incorrect or missing fire alarm device locations
Inadequate coverage information
Missing system calculations
Incorrect circuit or wiring information
Missing equipment specifications
Inconsistent information between drawings
Poor coordination with architectural, mechanical, electrical, or sprinkler plans
Missing required signatures or professional responsibility information
Failure to respond completely to previous correction comments
A correction notice does not necessarily mean that the entire project has failed. It means the plans need to be corrected and resubmitted for review.
What Is a Fire Alarm Plan Check?
A fire alarm plan check is a review of proposed fire alarm drawings and supporting documentation to determine whether the design satisfies applicable requirements.
For applicable projects, LAFD reviews fire/life-safety plans for compliance with national, state, and City requirements.
The review can involve items such as:
Fire alarm control equipment
Initiating devices
Notification appliances
Fire alarm circuits
Power supplies
Monitoring
Emergency interfaces
Device locations
Building characteristics
Occupancy
Fire/life-safety features
The purpose is to identify problems before installation and inspection, rather than discovering them after the system has already been installed.
Rejected vs. Returned for Corrections
Property owners sometimes use the word "rejected" to describe a fire alarm plan that receives correction comments.
In practice, a plan may be returned with specific corrections that need to be addressed before approval.
LAFD identifies correction notices as part of its plan-check process.
The typical process is:
Submit → Review → Corrections → Revise → Resubmit → Approval
The number of review cycles depends on the quality of the original submission and the complexity of the project.
Common Reason #1: Incomplete Floor Plans
One of the simplest ways to create plan-check problems is to submit drawings that do not clearly show the building conditions relevant to the fire alarm system.
Plans may need to clearly identify:
Rooms
Corridors
Stairways
Exits
Doors
Floor levels
Equipment rooms
Electrical rooms
Fire alarm equipment
Relevant building features
Fire alarm device locations
A reviewer needs enough information to understand how the proposed system interacts with the building.
How to Avoid This Problem
Before submitting the plans, verify that every applicable floor is clearly identified and that the fire alarm design can be understood without relying on assumptions.
Common Reason #2: Incorrect Device Locations
Fire alarm devices must be located appropriately for the building and system design.
Examples include:
Smoke detectors
Heat detectors
Manual fire alarm boxes
Horns
Strobes
Horn/strobes
Duct detectors
Waterflow monitoring
Tamper monitoring
Annunciators
A plan can encounter corrections when devices are shown in locations that do not satisfy the applicable requirements or when device placement does not correspond with the building layout.
Why Coordination Matters
Architectural changes can affect fire alarm device locations.
For example, moving a wall can change:
Room size
Corridor configuration
Detector locations
Notification appliance placement
Required coverage
Fire alarm plans should therefore be coordinated with the latest architectural drawings.
Common Reason #3: Missing or Inadequate Coverage Information
A fire alarm plan needs to demonstrate that the proposed devices provide the required protection for the applicable building areas.
Problems can arise when:
Required areas are missing devices
Device coverage is unclear
Ceiling conditions are not represented correctly
Room configurations are outdated
Device locations do not match the proposed architecture
A plan that simply places symbols on a floor plan without adequately demonstrating the system's design can create questions during review.
Common Reason #4: Incorrect or Missing System Calculations
Fire alarm systems can require calculations to demonstrate that the system will operate properly.
Depending on the system, calculations may address:
Battery capacity
Voltage drop
Notification appliance loading
Power supply capacity
Circuit loading
Standby requirements
Alarm requirements
If calculations are missing, inconsistent, or based on equipment that does not match the drawings, the plan may require correction.
Why Calculations Matter
The reviewer needs to know that the proposed equipment and power sources can support the system under the required operating conditions.
The design should therefore be internally consistent.
Common Reason #5: Inconsistent Equipment Information
A frequent problem is when the drawings, equipment schedule, specifications, and calculations do not agree.
For example:
The plan shows one fire alarm panel model.
The equipment schedule identifies another model.
The calculations use a third configuration.
Even if each item individually appears reasonable, the inconsistency can make the overall design difficult to verify.
How to Avoid It
Before submitting a plan, compare:
Equipment schedule
Floor plans
Riser diagram
Battery calculations
Voltage-drop calculations
Specifications
Device counts
The same equipment information should be used consistently throughout the package.
Common Reason #6: Missing Riser or System Information
A fire alarm floor plan shows where devices are located, but reviewers may also need to understand how the system is interconnected.
Depending on the project, documentation may include:
Riser diagrams
Circuit information
Panel information
Power supplies
Communication paths
Monitoring information
Interface connections
A plan that does not clearly communicate the overall system architecture may require additional information.
Common Reason #7: Problems With Notification Appliance Design
Fire alarm notification appliances must provide the required occupant notification.
These can include:
Horns
Strobes
Horn/strobes
Other notification appliances
Potential issues can include:
Incorrect device locations
Insufficient notification coverage
Incorrect candela information
Inconsistent device schedules
Missing calculations
Incorrect circuit loading
LADBS's fire alarm testing documentation specifically identifies strobe location and candela as items verified during the life-safety testing process.
This is one reason the notification appliance design should be carefully checked before submission.
Common Reason #8: Poor Coordination With HVAC Systems
Fire alarm systems can interact with mechanical equipment.
Depending on the building, the fire alarm system may interface with:
Air-conditioning systems
Air-handling units
Smoke control
Fire dampers
Exhaust systems
Building controls
LADBS's fire alarm testing documentation includes items related to A/C shutdown, fire dampers, smoke evacuation, building/auxiliary/outside air, and stairwell pressurization.
If the fire alarm design does not properly coordinate with the mechanical system, corrections can occur during review or inspection.
Common Reason #9: Fire Alarm Plans Do Not Match Sprinkler Plans
Fire alarm systems often monitor components of fire sprinkler systems.
These may include:
Waterflow switches
Valve supervisory/tamper switches
Other monitoring points
If sprinkler drawings and fire alarm drawings do not match, the project team may need to resolve the discrepancy.
Coordinate Early
The fire alarm contractor should review the applicable sprinkler design and coordinate monitoring points before finalizing the fire alarm plans.
Common Reason #10: Architectural Plans Changed After Fire Alarm Design
This is especially common in new construction and remodeling.
A project may change after the fire alarm drawings were prepared:
Walls are relocated
Rooms are added
Doors are moved
Ceilings change
Equipment rooms are relocated
Building areas change
If the fire alarm drawings are not updated, the submitted plans may no longer accurately represent the building.
Best Practice
Use the latest approved architectural drawings as the foundation for fire alarm design.
Common Reason #11: Missing Professional Responsibility Information
Los Angeles requirements can include specific responsibility and documentation requirements for fire alarm plans.
For example, an LADBS document concerning separate fire alarm plans states that the fire alarm plan must bear the stamp, signature, and date of a California registered professional Electrical Engineer or a licensed C-10 contractor responsible for the design and content of the plan.
This demonstrates why the responsible professional or contractor information should be checked before submission.
Common Reason #12: The Scope of Work Is Unclear
A plan reviewer needs to understand what the project is proposing.
A vague scope can create questions such as:
Is this a new system?
Is this an addition?
Is this a modification?
Is an existing panel being replaced?
Are existing devices being reused?
Is monitoring being changed?
Are new notification appliances being added?
The project description should accurately match the drawings and permit application.
Common Reason #13: Existing Conditions Are Not Properly Identified
For modifications to an existing fire alarm system, the reviewer needs to understand what currently exists and what is being changed.
Plans should clearly distinguish, where applicable:
Existing equipment
Existing devices
Existing wiring
New devices
New equipment
Removed devices
Modified circuits
This is especially important for tenant improvements and commercial remodels.
Common Reason #14: Plans Do Not Address Previous Corrections
If a plan was previously returned with corrections, the revised submission should address every applicable correction comment.
A common mistake is to correct one item while overlooking another.
Better Approach
Create a correction-response checklist:
Correction | Action Taken | Plan Reference |
Device location | Revised | Sheet FA-2 |
Battery calculation | Updated | Calculation Sheet |
Equipment schedule | Revised | Sheet FA-4 |
Riser diagram | Updated | Sheet FA-5 |
This makes the resubmission easier to review.
Common Reason #15: Fire Alarm Plans Are Not Coordinated With the Electrical Plans
Fire alarm systems involve electrical work.
LADBS identifies fire alarm systems as complicated electrical systems that generally require electrical plan check, subject to specified exceptions.
Problems can occur when the fire alarm plans and electrical documents show inconsistent information.
Examples include:
Different panel locations
Different power sources
Inconsistent circuit information
Missing dedicated power information
Conflicting equipment locations
Coordination between the fire alarm designer, electrical contractor, architect, and general contractor is therefore important.
Common Reason #16: Starting Installation Before Plan Approval
For applicable projects, installation should not be treated as something that can begin while the plan review is still unresolved.
An LADBS document concerning separate fire alarm plans states that the plans and specifications must be submitted before work is performed under that arrangement. It also states that the certificate of occupancy cannot be granted until the fire alarm permit is issued and inspection is finalized.
Starting too early can create significant rework if the approved design differs from what was installed.
Common Reason #17: Plans Are Not Ready for Final Inspection
Plan approval is only one stage of the process.
The installed system must also be ready for inspection and testing.
LADBS's fire alarm testing documentation states that approved plans and permits must be available and that the electrical inspector must perform the final electrical inspection before the
LAFD fire alarm test.
The document also identifies items involving:
Fire alarm wiring
Approved plans
Fire-rated penetrations
Door systems
Elevator recall
Emergency lighting
Exit paths
Mechanical interfaces
This demonstrates why plan preparation, installation, and final inspection need to be treated as one coordinated process.
How to Reduce Fire Alarm Plan Corrections
The best way to reduce corrections is to perform a detailed quality-control review before submitting the plans.
1. Verify the Project Address
Make sure the address and jurisdiction are correct.
2. Confirm the Occupancy
Verify the building's applicable occupancy information.
3. Use Current Architectural Plans
Do not design from outdated floor plans.
4. Verify Every Device
Check every:
Detector
Pull station
Horn
Strobe
Horn/strobe
Monitor module
Control module
Annunciator
Other applicable device
5. Check Equipment Consistency
Make sure the equipment schedule matches the drawings and calculations.
6. Review Calculations
Check:
Battery capacity
Voltage drop
Circuit loading
Power supplies
Notification appliance requirements
7. Coordinate Other Trades
Review:
Architectural plans
Electrical plans
HVAC plans
Sprinkler plans
Door plans
Elevator information
Emergency systems
8. Review the Entire Submission
Do not review only the floor plan.
Review the complete package before submission.
What Happens After a Fire Alarm Plan Is Corrected?
A typical process is:
Correction Notice → Revision → Response → Resubmission → Review → Approval
If additional corrections are identified, another revision may be necessary.
LAFD provides online plan-check and inspection services through its systems, and its Fire Development Services section handles plan review and correction notices for applicable projects.
The goal should be to submit a complete correction response rather than repeatedly addressing individual issues without reviewing the entire package.
